ELECTRICAL SPECIFICATIONS
*CAUTION*
This product incorporates numerous static-sensitive components.
Always wear an ESD wrist strap and observe proper ESD handling
procedures when working with this device. Failure to observe this
precaution may result in module damage or failure.

*NOTE* Exceeding any of the limits of this section may lead to permanent
damage to the device. Furthermore, extended operation at these maximum
ratings may reduce the life of this device.
1. *CRITICAL* In order to operate the device over this range, it is necessary for a 200
Ω resistor to be
placed in series with VCC.
2. Potential rate of data recovered on the DATA line (pin 10). The decoder rate is internally fixed at about
2kbps.
3. When operating from a 5V source, it is important to consider that the output will swing to well less than
5 volts as a result of the required dropping resistor. Please verify that the minimum voltage will meet the
high threshold requirement of the device to which data is being sent.
4. VCC referenced to voltage on the VCC pin after dropping resistor.
5. For a BER of 10-5 at 4,800 baud. Sensitivity is affected by the antenna’s SWR.
6. Time to valid data output.
7. Maximum drive capability of data outputs.

PERFORMANCE DATA
These performance parameters
are based on module operation at
25°C from a 3.0VDC supply unless
otherwise
noted.
Figure
2
illustrates
the
connections
necessary
for
testing
and
operation. It is recommended all
ground pins be connected to the
ground plane. The pins marked NC
have no electrical connection and
are designed only to add physical
support.
